Don't hink any B24s alive in 50s/60s.  90th bomb group 40s, eh?

Dave d'ya think this was a British system?  Note antennas look
mounted to a rectangular plate that's clobbled on  w. "100 mph tape"
Maybe a fighter'd drop a vhf beacon on target, etc.

Electronic switching wud be homing answer.  I read that & did a
H. Simpson D'oh.  One wud line B24 up so identical 'pip heights'
from L & R antennas.  Like lobe switching on 1st US 200mhz army
radar (scr268*).  But what Rx-en, what display?

Someone come back on this & make me do a 2nd D'oh.

Neat mystery
